Kate's take, in a sentence or two

Kate explains that her school community is exclusively for past buyers, so it's already a group of customers rather than cold leads—meaning school isn't converting subscribers into buyers, but rather turning buyers into repeat buyers through nurturing. She sees school and email as absolutely not mutually exclusive, but a "both and" approach, since her marketing philosophy is that everything sells everything through multiple touchpoints—she often repurposes content between the two platforms, and some sales happen directly in school when she posts something.
